Keep It Simple and Stupid

Hamsterdb tesing code (python)

Big file may slow down HamsterDB.(QPS 70 around 5,000,000 kvs)So test_write_en() / test_read_en() use pre-hash (mmh3).(QPS 300K around 5,000,000 kvs) That is not true, I made a mistake in my code and QPS is still around 70 with 5,000,000 kvs (even after the hash and split).
